IMPROVEMENT IN TOBACCO-PIPES.

Specification forming part of Letters Patent No. 45,380, dated December6, 1864.

To all whom it may concern.-

Be it known that I, LEVI K. BOWEN, of the city of Baltimore, in theState of Maryland, have invented a certain newand useful Improvement inTobacco-Pipes; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawing, and to the letters and marks thereon.

My improvement relates to that class or kind of pipes which have a cupor receptacle attached to the bottom of the bowl for the reception ofthe nicotine, saliva, and other offensive secretions, and, althoughspecially intended for the double-tube pipe patented in June, 1862, maybe used on any tobacco-pipe; and my improvement is upon the cup orreceptacle here named. Heretofore such cups have more commonly been madeof wood or horn, though they may be made of glass or porcelain. If madeof wood, by use they soon become offensive from being saturated withnicotine, saliva, &c. If made of horn, they are very liable to crack andsplit, and if made of glass or porcelain they are easily broken. Itherefore make such cups of metal, my preference being for an alloysomewhat resembling what is known as the yellow metal, though, ofcourse, other metals or alloys can be used. A metal cup or receptacle ismore durable than any other and cleanlier, while it can readily be madeby swaging with dies from wrought metal or by casting. If made of theshape shown by the drawing forming part of this specification, the cupmay be made of two pieces and brazed or soldered; or it may be made bycasting, if what is known as the divided core and flask be used inmaking it.

The cup a shown by the drawing is intended to be attached to the tip 1),extending from the bowl, by screw-threads out upon the inner surface ofthe cup and upon the exterior surface of the'tip; but, as is evident,the cup may be otherwise attached, either by screw into or upon the tipor without a screw, by sliding into or upon the tip or bowl, or by ahingefastening.

The cup represented by the drawing, it will be perceived, has a shortneck only-that part on which the screw-thread iswhile the tip is longerthan the neck of the cup. When the cup, therefore, is forced up againstthe bottom of the bowl, or, in other words, when in its position, thetip will extend within the cup, so that there will be an annular spacebetween the tip and inner surface of the bowl, the advantage derivedfrom this arrangement of the tip and cup being that the contents of thecup will not flow back into the tube when the pipe is turned or handledunless the quantity therein much exceeds the annular space here named,and even then not as readily as when the tip and neck of the cup are ofthe same length.

Cups of other forms than that here shown and described may be used, ifpreferred.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

The new article of manufacture above describedviz., a tobacco-pipe witha cup or receptacle constructed of metal.
